The fsmonitor module provides live filesystem monitoring. It can be used to monitor for events such as file creation, deletion, modification and so on:

from fsmonitor import FSMonitor

The FSMonitor class manages filesystem watches and is used to receive events. Call the add_dir_watch() method to add a directory watch to the monitor:

m = FSMonitor()
watch = m.add_dir_watch("/dir/to/watch")

Once a watch has been added, you can call read_events() to read a list of filesystem events. This is a blocking call and in some cases it might return an empty list, so it needs to be re-called repeatedly to get more events:

while True:
    for evt in m.read_events():
        print evt.action_name, evt.name

The FSMonitorThread class can be used to receive events asynchronously with a callback. The callback will be called from another thread so it is responsible for thread-safety. If a callback is not specified, the thread will collect events in a list which can be read by calling read_events().

See the example code in the examples directory.
